Investing.com -- Anthropic may begin formally marketing its IPO as early as Tuesday, Nov 10, 2026, testing whether the largest AI listing yet can clear a market that was rattled last week. Bloomberg reports the company is targeting an offering as large as SpaceX's record debut, or larger. The reported valuation talks have also fallen: some potential investors discussed $1.1T to $1.3T on Friday, down from the $1.5T to $2T range discussed earlier this month. The Nasdaq 100 fell 14% in the interim. (Market data as of Nov 9, 2026, 10:50 AM EST.)
The reason the debate has softened is that volatility has eased. The VIX briefly rose above 25 last week, a zone where Renaissance Capital's Matt Kennedy says companies typically postpone IPOs. It is now 20.73 (-19.15%). The S&P 500 is at 7,527.55 (+2.04%), and the PHLX Semiconductor Index is up 6.02% at 9,955.90. Kennedy argues Anthropic is in a different category, since "it just becomes a matter of where it prices."
The calendar is the real constraint. Marketing would begin straight after the 15-day waiting period that followed last month's public filing. That would put pricing and a Nasdaq Global Select debut in the week of Nov 16, ahead of Thanksgiving on Nov 26.
Anthropic's amended S-1 provides the numbers. Investing.com analysis of the filing (Nov 3, 2026) shows revenue of $16.96B in Q3, up from $11.56B in Q2. That is 47% sequential growth, down from 144% in Q2.
Annualizing Q3 gives about $67.8B. By this calculation, a $1.1T to $1.3T valuation equals roughly 16x to 19x that run rate, compared with 22.1x at $1.5T according to this analysis (Nov 4, 2026). The multiple is lower, but it is still high for a business whose growth is decelerating. The company's compute costs fell from 172% of revenue to 57% year over year (analysis, Nov 5, 2026), which supports the operating-leverage argument.

Slowing growth. Q3's 47% sequential increase is still large, but the direction matters when investors are paying for years of future growth.
Data-center politics. The Democratic midterm wins that triggered last week's selloff also threaten the capacity Anthropic depends on. The company says it must secure capacity 12 to 18 months ahead and has previously underestimated its needs. The prospectus cites roughly $70B of commitments due within 12 months.
AI safety policy. Anthropic backs slower development of the most advanced models, but AI-skeptic Democrats may push interventions that differ from its preferred solutions.
Supporters point to $95.6B in cash and $36.3B in short-term investments as of Sep 30, plus broad customer adoption. Shaires Holdings CEO Vivek Seth calls it a "once-in-a-generation company" and says the IPO will "establish a market-clearing valuation." Baillie Gifford's Peter Singlehurst says customers may pay more for models that reason better and work independently for longer. Kennedy adds that there is risk in not owning it.
A lower valuation could help. One analysis argues a weaker price can improve a deal by leaving room for execution risk. The offering also appears to leave the price range blank, which lets investors signal demand through bids. That contrasts with SpaceX (SPCX)'s $86.2B fixed-price IPO in June.
Retail participation may reach 20% of shares, with offers planned across the US, UK, Japan and Australia. The effect on public AI names runs both ways. A strong book would support suppliers and partners such as Alphabet (GOOGL) ($293.40, +3.03%) and, in the infrastructure complex, Nebius (NBIS) ($139.70, +7.88%). A poor reception would reinforce last week's doubts about whether AI valuations can hold. OpenAI is expected to follow with its own listing, so Anthropic's pricing may set the template for private AI valuations.
Anthropic has little time to wait, and the market has already lowered its valuation expectations by about 15% to 40% depending on the benchmark. Last week's selloff left potential buyers nursing losses, while fear of missing the biggest IPO ever is pulling the other way. Early indications of order-book quality, and where the range is set, will say more than the headline size.
